vide improved means for adjusting and securing pencil leads, needles, probes or the like therein.

According to this invention l provide a slotted holder with a sliding ring on the holder and a wedge disposed 1n the slot and under the ring and so arranged that the lead, probe, needle or the like is adapted to be gripped between the wedge and the holder when the ring is slipped or pressed over the wedging surface; stops are or may be provided on the upper surface of the Wedge and a spur on the underside thereof. Figure l is a sectional elevation of a holder as applied to a pencil provided with an adjusting and locking device made in accordance with the invention. Fig. 2 is a detail view of a wedge.

a is a holder provided with a central bore c is a longitudinal slit communicating with the central bore.

a? is a ring mounted to slide on the holder a, e is a'narrow wedge disposed in the slot c, f is the lead adapted to be gripped in the slot between the wedge and the holder.

The wedge e is provided 'with a front stop g, a rear sto L on the upper side and a spur j on the un er side. The wedge has a releasing surface m and a wedging surface ic, the holder is preferably pointed like a cedar pencil.

The mode of action is as follows :-Supposing the lead f to be Within its case a and it is desired to project it for writing or any other purpose, the slide-ring d is slid toward the point and ressing against the front stud g on the orward end of the wedge, `cants it a little, and the spur j above mentloned is lifted. On the sliding of the slide-ring d being continued, the wedge is moved bodily forward along the slit o toward the point, and the spur g pushes the lead f along until as much of it as is desired has protruded. The slide-ring is then slid backward and as it rides along the wedge it presses down at 7c the butt end protected position, and the slide-ring is then slid back to re-lock.

One great advanta e ofV my invention is that the pencil may described `very readily with one hand. Another advantage is that the position of the Slide-ring and Wedge (nearer to or farther away from the point) forms a reliable means for showing the length of lead contained in the case.

lt will be obvious that my invention is also applicable to probes, needles or other articles that are required to be protruded from, and held firmly in their cases or with drawn thereinto as desired.

rlhe holder may be made of Wood, metal or other suitable material.

In` a pencil holder made in accordance with this invention the lead may be projected for use and is very firmly retained in position. rlhe lead may be retracted and secured when not in use.

What l claim and desire to secure by Letters Patent is 1. ln holders for pencils, the combination of a slotted holder, a sliding ring on said holder, a wedge disposed in the slot and under the ring, said wedge being provided with a releasing surface, a wedging surface and a spur, said spur being adapted to engage the back of the lead and serve as e operated as abovel a. stop for the lead in all positions of the lat-ter and adapted to be pressed into enga ement with thebottom of the bore by the li ing ring coacting with the wedging, suraoe.
